The latest version of Science.gov—Science.gov 5.0—has been launched. Science.gov 5.0 allows users to search additional collections of science resources, target their searches, and find links to information on a variety of science topics. Science.gov 5.0 offers seven new databases and portals which allow researchers access pages of scientific information. Another feature of Science.gov 5.0 is a "clustering" tool which helps target searches by grouping results by subtopics or dates. Science.gov 5.0 now provides links to related EurekAlert! Science News and Wikipedia, and provides the capability to download research results into personal files or citation software.
